GENERATOR-TUBE AND FILLER FOR VAIOIL-STOVES.

Specification of Letters Patent. 7

Patented Nov. 28, 1911.

Application filed November 21, 1910. Serial No. 593,302.

-.To all whom it may concern:

estville, in the county of Hartford and State of Connecticut,have'invented certain new and useful Improvements in Generator- Tubesand Fillers for Vapor-Stoves, of which the following is a specification.I

My invention relates to improvements in generator tubes for liquid fuelvapor stoves, and the objects of my improvements are to provide anefficient interior cartridge or fillmg and to provide for cleaning thesame and the tube when they become foul.

In the accompanying drawing: Figure 1 is a plan view of a vapor stovewith one of my generator tubes applied thereto. Fig.- 2, is an enlargedcentral longitudinal section the generator tube, with a side elevationof the filling within the tube. Fig. is aside elevation of the combinedcore and handle for the said filling. Fig. 4: is an enlarged transversesection on the line ac w of Fig. 1.

My generator tubes are designed for vapor stoves which use liquid fuelthat is fed by gravity into the generator tube from an elevated font.-As shown, the generator tube llvextends diametrically across the stovebelow a ring-shaped burner 5 that is fed from the font 6.

My improvement relates to the filling within the generator tube, whichfilling is detachable from the tube proper in its en'- tirety. Otherfillings in this class of tube have been designated as cartridges. Themanner of connecting the tube with the burner and font is not essentialto my invention so long as a portion of the tube constitutes acompartment or chamber in which vapor is generated from the liquid fuelthat is fed int-o the tube for supplying the burner with vapor. The tubeproper 14: is of an old construction and in fact the stove herein.illustrated is made in accordance with the Varner Patent No. 968,435,

Aug. 23, 1910, with theeXception of the parts within the generator tube.

The main portion of my cartridge or fill-z ,ing is composed of a bundleof longitudinally extended wires. 'lhesebroadly speaking are old andwell known as a filling for generator tubes.

I employ a core or foundation upon winch to build up thecartridge, thesaid core consisting of a twisted wire handle 8 and two make thempractically a solid plug 11 at' that end. The outer wires are cut awayor reduced to about half their diameter at the plug end for the fulllength of the said plug or soldered portion, so that the said plug is ofless diameter than is the bunch of wires at the other parts of itslength. That end of the generator tube which is occupied by the plug andfrom which the handle projects, is the influent end of the tube, and theplug is made of less diameter than the full bunch of wires in order tolet the liquid fuel pass through the tube around the plug at this pointinto the spaces between the several wires and between the outer wiresand the inner wall of the tube. The several wires are flexible and theirends farthest from the influent end of the tube are left free andunfastened excepting the ends of the two central wires 9. Theseterminate within the tube at a point beneath the ringshaped burner.

The filling thus far described will form 3 an eiiicient and operativedevice, but I prefer to add other parts as follows: A cleaner 12 in theform of a wire brush is secured to the shank 13 which shank is anextension'ot' the central wires 9, the said cleaner filling the tube ata point near the eflluent end thereof, leaving an open space or chamberwithin the tube around the brush shank be tween the said brush and theconfronting ends of the wires 10. The -fuel enters the generator fromthe front branch 17,:1nd the end of the generator tube may be closed byremova le cap 18. The vapor is discharged from the tube through suitableand ordinary cock, that may be inserted into and secured to thegenerating tube. The handle 1.5 and needle 16 of the said cock in Fig.1.

The general operation of the stove, in generating vapor from the fuel,the same as in other stoves of this class. iYhcn denaturcd alcohol isemployed as the fuel in these stores, it generally follows that afterare sh own.

.a time, a hard gummy substance is, deposited within the generator tubeat a point, near the burner, or the part of the tube that is sub-'jected to the highest heat, which substance gradually cuts off the flowof the fuel and vapor, thereby rendering the stove less useful if notwholly useless. A filling of longitudinal wires for the generator tubedistributes the fuel over a large surface and at the same time gives themost eificient feed for alcohol containing a gummy substance. By'smyimprovement, when the generator -tube becomes foul so as to impair theusefulness of the stove, it is only'necessary to withdraw the entirefilling from the generator tube and then separate the free ends of the.wires 10 and clean them thoroughly, in anyproper' manner. Theflexibility of the wires and leaving their ends free as described,permits of complete separation of the wires 10, so that they may becleaned one byone, or they will be flexed and rub' one against the otherif-the bunch of'wires 10 be rolled back. and forth under pressure.Pulling the wires from the generator tube will break up and loosen thegummy substance that may lie between the Wires and the wall of the saidtube, and the cleaner,

scraper, or brush 12, following the said wires, will remove allot theloosened. forelgn matter and also loosen and remove other portions thatmay not have been loosened in removing the wires.- When thusf D cleanedthe filling or cartridge'forthe gener- 35 stove] will be substantiallyas efficient as ator tube is replaced therein after which the when itwas new, and this. cleaning-'canbe repeated as often as may be desired.1

The construction is simple and inexpensive, and the entire filling maybe'removed as a unit.
